Progressively getting worse.

Yesterday in the morning the game was working perfectly,then a night is was a mess. Players with pings all over the place,the bots are shooting through obstacles and bots and players appearing out of nowhere and several cheaters running around and rounds going through other players.Wtf? Are they going to let this game slip or what?and why do the tanks move on their own? So many problems which shouldn't be happening with all the experience from the other battlefields.
